Abstract
The identification of biological aerosols is asubject of worldwide interest because of the potential forbiological terrorism and the increase in public healthemergencies. Laser-induced fluorescence is widely used toinvestigate the fluorescence properties of biomolecules andspores in solution; however, data on the fluorescence propertiesof the aerosolized forms are lacking. In this study, we report thefluorescence properties of tryptophan, serotonin, tyrosine,vitamin B6, and Bacillus thuringiensis and Bacillus subtilisspores in solution and aerosol form. Our results show thatthe shapes of the fluorescence spectra were generally consistentbetween the solution and aerosol states despite some wavelengthshifts in the emission spectra. In contrast, the fluorescenceintensity of the emissions varied significantly between thesolutions and aerosols. Given the growing global interest inaccurate measurement of airborne biological molecules andparticles, our findings provide a useful baseline for furtherresearch into the development of laser-inducedfluorescence-based bioaerosol detection instruments and canguide the ongoing design of effective measurement andengineering technologies.
